low pH problems
Grrrowerstarted grow question 5y ago
I discovered that I had irrigated with water at pH 3.5 for at least 5 days.
yesterday I used water at pH 5.7 and today I think it will increase to 6, but I noticed that burns are already starting to appear so should I continue like this and hope for the best or do a root wash?

I think the only way to know is to check the runoff when watering and see what PH it gives you.. if it's in an ok range, then just leave it (don't try to compensate), as the damage was done and you don't want to push it the other direction, possibly making it worse.. the marks on the leaves will not recover, but check the new growth to ensure that this is fine moving forward.
If you're in soil, i'd rather err on the higher side, so around 6.3, as 5.7/5.8 is more for hydroponics..

Hi I would flush the whole thing to make sure :-). Adjust the Ph and Ec value of the water and rinse it :-) to luck you have it right on time :-)

damage was done, so you could expect some minor burning. As long as you adjust the ph, all should be grand. In soil growing the pH is getting alkaline with the drying of the soil between watering. That is why you have to water well until you get a run off in the tray, to flush out the alkalinity from the middle of the root ball. Don't get over stressed about the pH in the water or to have it at just the right value. Plant will do just fine with water pH 7.

White Widow runoff water tests at 2440 PPM, but seems happy still and is only showing very slight signs of burning. This still seems extremely high, so I've backed off on feeding for now and watered with some Cal Mag. Should I wait for the PPM to drop or keep feeding her at 1/4?Week 11

Should I Foliar Feed After 2nd Week Flower?I've been toying with the idea of a foliar feed during flower. I normally don't do any foliar feeds after the second week of flower, just to help prevent contamination or buildup of non-medicines in my final product. Any suggestions as to what i should feed my lil purple budling?Week 3

pH woes. To water or not to water, that is the question.The tap water I've been watering my plants with is very alkaline, the pH came out to around 10 when I measured it with a digital reader. Should I water it again with pH adjusted water early or wait until the soil dries out to avoid overwatering? Soil and nutes pH was ~8.6.Week 3

Feeding rain water from distilled waterHello everyone,
Currently I’m using distilled water to feed my plants and i collected some buckets of rain water for the past few days. I checked the ph level and it’s a bit high. I have ph down and up to adjust it. Is it ok to switch using the rain water with added nutrients?

Increase nutrition?Should I up the nutes? I’ve been feeding 1/4 amount for the last 3 feeds. I’ve read that after first week of 1/4 up it to 1/2, but from what I can see (foliage pic added) everything looks like it’s quite healthy.
Will plant benefit with more or should I stay as I am?
Cheers

Calcium excess, which led to potassium deficiency? Or just light burn? Or both? What's wrong with my girl? Please, help.I've been giving her BioBizz in accordance with the schedule, including CalMag. Using tap water (250-300 ppm). So my only guess is calcium excess, which led to potassium deficiency.
However, only the main cola is affected now. So I also suspect light burn.
What's your opinion?
